3.) Two cars are traveling side by side on level terrain at 100 km/h on a road with a coefficient of adhesion of 0.8. The driver of car 1 has a 2.5-s perception/reaction time and the driver of car 2 has a 2.1-s perception/reaction time. The drivers are able to stop their respective cars in the same distance after seeing a roadway obstacle. If the braking efficiency of car 2 is 0.78, determine the braking efficiency of car 1. (Assume minimum theoretical stopping distance.) Note: mass factor=1.04, gravitational acceleration=9.807 m/s?
